Highest Amperage Stator for the 103"
Does anyone make a higher amp stator than the 45amp that comes standard on the 103"?
I need to beef up the charging system and not finding much info on this.

If you are adding a big stereo amp or heated clothing etc. How about an aux battery in the saddlebag ?
The bike charging system would be able to keep both batteries charged up and you'd have the reserve you need.
another "work-around" is to convert from incandescent to LED lighting- every 100 watts of incandescent uses 8.5 amps- you could free up most of that with LEDS.
Cycle electric offers a 50 amp stator for your bike.
The reason we don't have 200 amp alternators in our bikes is because of the constant drag they would put on the motor and also the heat.
so a 45 amp is a compromise...should be enough power for all the junk we run.
it is possible that in the future we will see 24 or higher volt systems on our bikes, less current ( 1/2) would be required and wire 1/2 the gauge too, so less weight.
In an automotive application this could save hundreds of pounds ( so MPG)

I am just looking to see if there is something out there in a "performance" grade stator that will offer a little more amp's. I need all I can get.

as above: cycle electric offers a 50 amp stator.
what is the current draw of the amp ?
...and why would a 2nd battery not help you ?
lack of space or... ?
the kid on the next block who used* to rattle my windows had aux batteries for his system, as do many with large sound systems or other electrical loads.
Mike
* his Dad got sick of it too.

I know there is nothing that will solve my problem but I am hoping that there are higher amperage stators out there that could lessen my problem.
I don't know for sure how many amp's I pull with the volume at or near max but I am guessing in the neighborhood of 60-70 amp draw at max volume not including any other electrical.
This is just a guess because it is difficult to calculate, even though max is 1200 watts, it only pulls that at peak notes and notes inbetween where there is no sound is little to zero watts.
Averaged out, it very well could be much lower than my guestimate but I do know I am pushing the envelope of what the stator can do.
I do know that the higher the amperage of the stator, the less abuse it will see trying to power a 1200 watt sound system.

the load of your amplifier ( in amps) should be on the packaging or manual..
( or power consumption in watts and we can calculate the amp load using ohms law...at 12 volts, 8.33 amps for every 100 watts power consumption---
(not the 1200 watts music output)
or what size fuse came with it? that would indicate the manufacturer has determined that the amplifier draws less than which ever value fuse it supplied.
an aux battery will supply power. again it can be calculated by amplifier current draw and the amp hour capacity of the battery.
the charging system on the bike would restore charge to the aux battery at those times when the current draw does not exceed the 45 amps...
it's gotta be less than opening up and installing a stator and regulator.

I understand what you are saying. But installing a stator is really not a big deal to me. It is no different than any other mod we do to our bikes. And in my case, it is just another part of the sound system that I installed.
It's not a must do thing but if there is a higher amp rated stator out there, I intend to get it.
The whole point of me looking for this, is to increase the time I get to jam without draining my battery or batteries.
Thanks for the help but you are trying to steer me in the direction of just dealing with what I have the best I can instead of trying to improve upon what I if if there is an option out there.
As far as "dealing with it" goes? I intend to buy another battery just for that purpose. But I also intend to increase my charging capability if such an increase is even possible.
In other words, I intend to "Have my cake and eat it too".

You might try sending him a PM, he hasn't posted since 2017...
As stated in this thread, Cycle Electric still makes a 50 amp stator for 103" Twin Cams... That is the largest stator for a 103" I am aware of...
